Water pump AISIN or OEM Volkswagen

With these cars, it\u2019s less so staying on top of the regular service items from the dealer - and more so staying educated on all the little unspoken chickenshit maintenance items that VW doesn\u2019t outwardly talk about.

When I drove a Volvo I just did a belt and water pump every year. OE Aisin one every time.

Aisin is what my shop used when mine started to die at 140k. No problems so far at 150k

I actually just changed the pump on my 2018. With the pump/thermostat assembly, and a collection of specific tools, it cost me ~$900. I was quoted 2k by a dealer so I saved a good chunk of change. All-in-all the job is straightforward, save plenty of headache with disconnecting hoses and wire clips.

No problems other than the water pump

Welcome to the club of probably needing to replace your water pump & thermostat housing \ud83e\udee1

I used the same kit on my tl and the water pump started leaking 2 years in.

I went with a aisin kit and at the 2 year mark the water pump went.

The Aisin kits are fine. I would not use a gates kit; the water pumps are junk and so are the tensioners

I want to share a brief but critical report regarding the recent replacement of the engine's electric water pump (EWP) on my Prius Gen 4. The analysis of the data logs revealed an alarming scenario; the new aftermarket pump's performance was completely unreliable, showing clear evidence of torque failure and instability. I had no choice but to purchase the Original Equipment Manufacturer (OEM) pump from the dealership (it was stamped with the AISIN logo). The problem was instantly and definitively solved.
